E-paper hacking: fastest possible refresh rate
推荐理由
Here's a fascinating video on how these displays work, and how you can modify the firmware of the driver to get faster refresh rates
说明
这是2017年由Applied Science发布的一部教程,主题归在Consumer devices & gadgets。它讲的是e-paper display hacking这一支里的具体问题,而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成:Ben Krasnow of Applied Science explains how electrophoretic e-paper displays work and how he modified the driver firmware and waveform lookup tables of a 4.2-inch panel to reach roughly 3Hz partial refresh. It covers the tweakable constants in the refresh process and touches on colored e-ink microcapsules.这些读者给出的理由,核心是:Whenever e-ink refresh speed or driving waveforms come up, HN points to this as the clearest hands-on explanation of how these displays work and how to hack them.讲法不绑某一条新闻,过几年仍然可以当材料看。从2018年到2021年,有4位不同的读者在4个不同月份把它推荐出来,其中明确叫别人去看的有1次。适合打开电脑跟着做的人。如果只听不练,这集的价值会少一半。如果已经会了基本定义,就把注意力放在它怎么把e-paper display hacking变成能跟着复述的例子。
